Artificially hatching eggs

Recommended Posts

Hi all,

I managed to save a good amount of eggs (70-80) from a golden neocaridina and am attempting to hatch them in an egg tumbler. I noticed that they started to grow a white fuzzy-like growth around them, which may be attributed to the clear membrane that I was too lazy to remove or the notorious, deadly fungal growth. I'm more-so experienced in raising Corydoras than shrimps, and these would be removed from the tumbler to avoid fouling the rest. However, I spoke to an experienced breeder who stated that she had successfully hatched ones like these, and so I thought that there would be no harm in trying (in a separate tumbler).

I promptly removed the eggs and performed a dip in a diluted methylene blue bath. Will see how they go.

Good luck with this, there are a few on here that have succeeded doing this so it is worth trying!

Good luck! I'm doing the same thing right now with some tangerine tiger eggs dropped in a moult, I don't have a tumbler though so I'm using a net over an airstone.

Hey guys,

Guess today was the day. This was one of many. I was doing a dip every 2-3 days, for about 5 seconds, whether it helped or not, I'm not entirely sure!

FANTASTIC! You must be thrilled and all the effort was was clearly worth it. They will be very fragile so you aren't totally there yet as they could still perish but I have my fingers crossed and well done!

Thanks Simon! It was a nice surprise, especially with the ongoing issues with the tank. I might stop h2o2 treatment now with them being born and all.. What are your personal go to foods for keeping them alive? and feeding frequency?

Are they in the tank or separate? In an established tank they will probably just survive on biofilm, especially if there is a limit number of them. I use Bacter AE which encourages biofilm growth and I'm not sure whether the shrimp eat it as well as they sually make a beeline for it? I used to feed the shrimp a Chi Ebi baby shrimp food. Both bacter AE and thebaby shrimp food are powder and I dip about 5mm of a wooden stick (match etc) in the water, then into the product, knock off excess, and then swirl in the tank! I did this twice a week. I don't honestly know whether feeding the babies made any difference but the tank was very well stocked with shrimp by that stage, so it probably must have helped. There are a few baby shrimp foods, most makes do one and they will be powder.

If you move them from one tank to another you should drip acclimate them over a good few hours, even if the parameters are pretty similar, especially when they so small/young.

Baby shrimp tend not to move far from one spot to start with and hide often so you may not see much of them in a normal aquarium setting until they have settled in.

Congrats and well done on hatching your shrimp artificially.

      No problem, but that doesn't explain your shrimp deaths. Those addition water parameters we asked for will help us narrow it down.

      Oh I see! That makes sense. Thank you so much for your help 🙂

      Not necessarily a cause of disease. When shrimp die, they loose the pigment under the shell turning them an orange like when you see when you cook prawns to eat.  The colour you see on shrimp is under the shell (notice when they moult, they don't loose colour), and when this colour pigment is destroyed, they turn orange. What you are seeing is normal for a dead shrimp. But if you see a live shrimp with pale orange internals, than that could be an internal infection caused by disease.

      Okay, an update: my fiancee pointed out that all of the dead shrimp have bright pink/orange internal organs, which they did not have previously. After a brief google search, it could potentially be some sort of disease? If so, do I need to dump the entire tank before starting a fresh cycle? It's a planted tank so it'd be a bit more of a pain to drain I would think. Now I'm thinking, if it isn't the drip acclimation problem or the water hardness (so many potential issues), the new shrimp may have been infected and passed it on to the older shrimp.

      I did not drip acclimate them; that was probably at least part of it, huh? Good to know about dripping in the water during maintenance as well! Unfortunately, over the night, the remaining two shrimp died as well 😞 It's very disappointing, but I've learned a lot and I know a lot of what to change for the future batch. They are neocaridina, and that video was very helpful, thank you!! I've watched shrimp keeping videos before, but that was the most thorough and easy to understand, so I appreciate it 🙂 I will definitely also get KH/TDS/GH testers in addition to the pH/ammonia/nitrite/nitrate I already have.
